Pet Rocks are simple, inanimate objects that became a popular fad in the 1970s. Created by advertising executive Gary Dahl, these rocks were sold in cardboard boxes with air holes and a care manual, making them seem like real pets. The idea was to provide a low-maintenance companion that required no feeding, grooming, or walking. The Pet Rock phenomenon quickly gained popularity, with millions sold in a short time. They were often painted or decorated, and many people enjoyed the novelty of having a rock as a pet. Although the trend faded, Pet Rocks remain a memorable example of quirky marketing and consumer culture.
